All the internet companies that are reported to be involved in Prism all gave the same and interesting reponses. I am very doubtful about the truthfullness of all of these responses. I think these companies know about prism but are giving a uniformed response in various forms. I think these companies are under a contract, promise or court order by the government not disclose anything.

Microsoft: "We provide customer data only when we receive a legally binding order or subpoena to do so, and never on a voluntary basis. In addition we only ever comply with orders for requests about specific accounts or identifiers. If the government has a broader voluntary national security program to gather customer data we don't participate in it."[23]

Yahoo: "Yahoo! takes users' privacy very seriously. We do not provide the government with direct access to our servers, systems, or network."[23]

Facebook: "We do not provide any government organization with direct access to Facebook servers. When Facebook is asked for data or information about specific individuals, we carefully scrutinize any such request for compliance with all applicable laws, and provide information only to the extent required by law."[23]

Google: "Google cares deeply about the security of our users' data. We disclose user data to government in accordance with the law, and we review all such requests carefully. From time to time, people allege that we have created a government ‘back door' into our systems, but Google does not have a backdoor for the government to access private user data."[23]

Apple: "We have never heard of PRISM. We do not provide any government agency with direct access to our servers, and any government agency requesting customer data must get a court order."[24]

Dropbox: "We've seen reports that Dropbox might be asked to participate in a government program called PRISM. We are not part of any such program and remain committed to protecting our users' privacy."[23]

Of course they'll deny it. Do you really think they'll admit to sharing your personal information with the NSA? Us innocent people are being treated like terrorists, its disgusting it really is. Prisim should only target suspected terrorists and crime syndicates and they should have a court order to do so.
